HALF OF HIS RIGHT TO WILLIAM S. BOSS, JR,

OF SAME PLACE.

PENCILI-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 228,923, dated June 15, 1880.

' Application filed April 29,1880. (No model.).

To all whom it may concern:

Be it known that I, EUGENE E. NORTON, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Pencil-Sharpeners,

and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My invention relates to a tool or implement to be used for the purpose of sharpening the points upon ordinary cedar or other wooden pencils.

Heretofore most pencil-Sharpeners have cut away the wood from the central lead around the pencil, or in a direction sidewise to the grain of the wood. This operation has torn out the wood wherever .the grain was uneven, and if the cutter comes in contact with the lead it breaks it of.

The object of my invention is to cut the wood and lead lengthwise while the pencil is held at the proper angle, and thereby avoid the difficulties above mentioned.

In the accompanying drawings,which illustrate my invention, Figure l is a top view of my improved pencil-sharpener. Fig. 2 is a side view of the same. Fig. 3 is a longitudinal section through the middle. Fig. 4 is a front-end view.

A is a block which carries the pencil, fitted within a box or casing, B, and sliding back and forth in the cutting or sharpening of the pencil. The throw is limited by the pin C, which moves in the slot A of the block A, so that the block will not draw out from the casing B. The block A has an opening through it diagonally, as shown in Fig. 3, through which the pencil passes.

At the rear end of the block Ais the revolving holder or clamp D. This fits into a socket in A, and is held therein by means of a pin, E. The rear end of D is split and is provided with the sliding ring G, which binds the sides of D together by being moved to the rear. For this purpose the exterior of the holder D is made slightly conical, as shown in the drawings.

H is the knife or cut-ter. It is fitted into the top of the box B, and is held firmly in place by means of the set-screw J. The cutting-edge of H is in line with the front edge of the box and just above the top of the carrier A. In the drawings the knife is shown as slipped into a socket in the top of the box B; but it may be attached in any convenient manner so as to bring the edge in the proper position.

The operation of my invention is as follows: The pencil is inserted through the opening in the block A and the clamp D. It is then clamped by drawing the ring Gr back and holding the pencil in such a position that the end of the lead will come in line with the top of the sliding block A, or in the position shown in Figs. 1 and 3. The sliding block A is then drawn back into the position shown in Fig. 2, which cuts off the wood in a diagonal direction from the outer surface to the lead point. The pencil is then rotated through a small angle, the carrying-block again pushed forward and again another slice of the wood; and this operation is repeated, turning the pencil a short distance round at each cutting, until the whole is sharpened to a point.

What I claim as my invention is- 1. A pencil sharpener composed of two parts sliding longitudinally upon each other, one furnished with a device for holding the pencil at the proper angle, and the other furnished with a knife for cutting the pencil longitudinally, substantially as described.

2. The combination of the sliding carryingblock A, the rotating clamp D, and the case B, provided with a cutter, H, to form a pencilsharpener, substantially as described.
